Article Abstract
Background: To evaluate the clinical efficacy of a novel surgical technique using a 25-gauge active aspiration of flute needle for treating the dislocation of posterior intraocular lens (IOL).
Methods: This retrospective study included 12 eyes in 12 patients with posterior dislocated IOL. All patients underwent comprehensive ophthalmic evaluations before surgery. Surgery was performed with three-port pars plana vitrectomy, the dislocated IOL was aspirated to the anterior vitreous by a 25-gauge flute needle, and then managed by different surgical corrections. Comprehensive ophthalmologic assessment was performed preoperatively and postoperatively, including best-corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp biomicroscopy and fundus examination. Postoperative assessments were conducted at 1 week, 1 month, and 3 months.
Results: Twelve eyes were treated. All surgeries were successfully completed using a 25-gauge silicone tip with active aspiration. IOL repositioning without sutures in 1 case (8.3%), IOL repositioning with scleral sutures in 4 cases (33.3%), IOL exchanged with Yamane technique in 4 cases (33.3%) and IOL exchange with scleral sutures in 3 cases (25.0%). The mean follow-up time was 13.08 ± 5.49months (range 5–20 months). The mean BCVA preoperatively was log MAR 0.48 ± 0.33 (range 0.0-1.3), recovered to log MAR 0.34 ± 0.22 (range 0.0-0.7) at three-month postoperatively. The BCVA was improved at the three-month follow-up compared with preoperatively (t = 2.40, = 0.035 < 0.05). IOP remained stable except for one patient who developed transient high IOP, but well controlled by medications.
Conclusions: An active aspiration of flute needle with silicon tip provides a simplified, efficient and safe method for IOL dislocation, minimizing the needs of perfluorocarbon liquids as well as intraocular-forceps.

Department of Ophthalmology, Northwell Health Eye Institute, Great Neck, NY, USA.
Purpose: To report five cases of structural weakness at the haptic-optic junction of the CT Lucia 602 intraocular lens (IOL) (Carl Zeiss Meditec Inc., Dublin, CA), including two optic breakages and three optic microfractures, while using the Yamane flanged intrascleral haptic fixation surgery (FIHFS).
Methods: A retrospective chart review of five cases that underwent Yamane FIHFS by the same surgeon between 2020 and 2022 was performed.

Purpose: To investigate the mechanism, intraoperative characteristics, management, and prevention of incision capsular bag herniation (ICBH), a previously unreported complication during cataract surgery in eyes with lens subluxation.
Methods: A retrospective observational case series was conducted on five male patients who developed ICBH during phacoemulsification with intraocular lens (IOL) implantation between January 2019 and December 2024. Among 867 subluxated-lens surgeries performed during this period, the estimated incidence of ICBH was 0.

September 2025
Purpose: To evaluate tilt, decentration, and axial stability of the Clareon toric intraocular lens (TIOL) (CNW0T3-9; Alcon Laboratories, Inc) over a 6-month follow-up period.
Methods: A single-center, prospective, interventional clinical trial was conducted with a study population of 130 eyes from 82 patients who received a Clareon TIOL. Tilt, decentration, and the aqueous depth were determined preoperatively and at 1 week and 6 months postoperatively using anterior segment optical coherence tomography (Casia 2; Tomey Corporation).
Purpose: To evaluate visual and refractive outcomes, visual quality, patient satisfaction, and spectacle independence 3 months after phacoemulsification with bilateral non-diffractive enhanced depth of focus (EDOF) lens implantation.
Methods: This study included 68 eyes of 34 consecutive patients, with 51.5% undergoing refractive lens exchange and 48.
